title: 'Gammapy: Python toolbox for gamma-ray astronomy'
abstract: 'Gammapy analyzes gamma-ray data and creates sky images, spectra and lightcurves,
  from event lists and instrument response information; it can also determine the
  position, morphology and spectra of gamma-ray sources. It is used to analyze data
  from H.E.S.S., Fermi-LAT, HAWC, and the Cherenkov Telescope Array (CTA).'
